Second segment of Rocket to the Stars contains a preview of the Program's Hands on Activity which allows students to investigate the relationship between height a marble is released and distance a milk carton will travel once the marble hits the milk carton.

The NASA Explorer School students from Martinsville Middle School in Martinsville, Virginia, will 00:00:00
preview this program's hands-on activity. 00:00:08
Hi. 00:00:11
NASA Connect asked us to show you this program's hands-on activity. 00:00:12
In this activity, students will do an inquiry investigation on the relationship between 00:00:18
the height from which a marble on a ramp is released and the distance a milk carton at 00:00:23
the end of the ramp is moved along the floor after the ball collides with the carton. 00:00:27
You can download a copy of the Educator's Guide from the NASA Connect website for directions 00:00:32
and a list of materials. 00:00:36
Before you start the activity, your teacher will ask you to answer and discuss several 00:00:39
critical thinking questions based on the experimental setup. 00:00:45
Set up the ramp by using tape to mark one end 0.7 meters high and place an empty milk 00:00:50
carton at the other end of the ramp so that it will catch the marble after it rolls down 00:00:57
the ramp. 00:01:01
You will roll a marble from five different measured heights. 00:01:02
Line up a meter stick on the floor along the distance that the milk carton will travel 00:01:07
after being hit by the marble. 00:01:12
Starting at the first height marked on the ramp, release the marble down the ramp. 00:01:16
On the data collection chart under Trial 1, record the linear distance that the milk 00:01:21
carton travels after the marble hit it. 00:01:27
You will conduct four more trials. 00:01:31
Record the distance the milk carton travels. 00:01:35
Calculate and record the average distance the milk carton traveled. 00:01:38
Continue the experiment by increasing the height from which you drop the marble by 0.1 00:01:44
meter each time. 00:01:50
Students will analyze their data by calculating the potential energy that the marble has at 00:01:52
each height and the kinetic energy that the marble has at the end of each roll. 00:01:58
Now is your chance to put your algebra skills to the test. 00:02:04
Keep in mind that for this activity, you will need to ignore energy lost because of friction. 00:02:08
Based on the data you collect, you will graphically show the relationship between the height from 00:02:16
which the marble is dropped and the distance the carton is moved. 00:02:22
From the graph, select another designated height and predict how far the milk carton 00:02:28
will move if the marble is released. 00:02:33
Go ahead and test your prediction. 00:02:35
Were you correct? 00:02:38
Don't forget to check out the web activity for this program. 00:02:39
You can download it from the NASA Connect website. 00:02:44
